In 2012 I built some code to scrape my WikiLog (not in real-time) to put the page-graph into some relational tables on a different server, and use JavaScript widgets to provide VisibleBacklinks near the bottom of every page of the WikiLog. http://webseitz.fluxent.com/wiki/WikiGraph

* I hacked together some D3 code from other people's work to make a little browser of that local page-graph. So at the end of that little widget of Backlinks at the bottom of every page is a link labelled "click here for WikiGraphBrowser" which launches a new window that gives the cluster of pages linked in either direction to that current WikiLog page. Then you can double-click on any node to add its neighbors to the graph. http://webseitz.fluxent.com/wiki/WikiGraphBrowser
